Finally, I have some time to get back into tinkering with circuits again!
I was wondering about some of the benefits and pitfalls of using passive RC filters and buffer stages before and after the filter versus using active filters?
I like the simplicity of using passive RC filters, and in most cases making them adjustable is relatively easy versus using active methods where I may need multi-deck switches to switch several capacitors/resistors at the same time.
I guess my question is essentially, is there anything inherently bad about using passive RC filters and using buffers around them to compensate for loading issues?
